Openreach ONT with BBU in enclosure

This page is about the FTTP termination device that Openreach install for FTTP customers.

Older Openreach ONT (Optical Network Termination) such as the one pictured, is actually inside the enclosure. This also contains a Battery Backup Unit (BBU) along with various wiring and cable management.

Newer ONT installs do not include the BBU, and are also not in a larger enclosure.

The ONT requires power, so will need a mains power socket nearby.
